Chen Zijin was a poor scholar who came to Beijing to take the exam. The test questions were exactly the same as his dream last night. He suspected that someone was leaking the test questions, and investigation revealed that the examiner was his biological father - his father abandoned his wife and son back then and now wanted to compensate by leaking the test questions. Chen Zijin refused to cheat, and his father threatened to disqualify him from the exam. He wrote an expose document overnight and distributed it outside the examination room. In the end, his father was dismissed, and he won the first prize in the examination based on his true talent and learning.
